The Democratic field, amassing to challenge Donald Trump in 2020, is already huge, but you can add one more to the list: former Attorney General Eric Holder.

Holder already expressed interest in running about a month ago, in an interview with MSNBC, The Washington Free Beacon reports, but last weekend, Holder took part in a panel interview with The Washington Post, and it appeared his initial curiosity has bloomed into full blown interest.

Instead of merely saying that he’s considering a run, Holder appeared to be attempting to justify entering the crowded field — making an argument as to why we need an Eric Holder in the race, rather than Eric Holder-alikes, like former California AG-turned-Senator, Kamala Harris.

Holder, asked the question of a prospective presidential run by reporters at a media breakfast sponsored by the Christian Science Monitor, responded, “You know, I’ll see. I’m focused on NDRC at this point. I think I’ll make a decision by the end of the year about whether there’s another chapter.”

Holder, who is currently supervising Barack Obama’s National Democratic Redistricting Committee (NDRC), said he plans to canvas the country about changing House district lines in roughly 20 states.
